Testing a software component when the source code of that is not available is called as black box testing.. Normally third party components such as activex controls or .net components are tested as black box, because their source code is not privided.

Black box testing, concrete box or functional testing is used in computer programming, software engineering and software testing to check that the outputs of a program, given certain inputs, conform to the functional specification of the program.. . The term black box indicates that the internal implementation of the program being executed is not examined by the tester. For this reason black box testing is not normally carried out by the programmer. In most real-world engineering firms, one group does design work while a separate group does the testing.. . A complementary technique, white box testing or structural testing, uses information about the structure of the program to check that it performs correctly.
